During the summer of 1927, the celebration of the Diamond Jubilee of Confederation was fittingly carried out. A committee appointed by the government in connection with the celebrations suggested a special issue of postage stamps to commemorate the occasion. The subjects of these commemorative stamps centred around the statesmen and the events they commemorated. The stamps were bilingual with the words "Postes" and "Post."

Map of Canada, showing the political boundaries in 1867 and 1927.
